ABSTRACT:
A mowing machine has an elongated beam that supports side-by-side rotors with pivoted cutters positioned to cut overlapping paths in front of the beam. The rotor units include an upper rotatably hub with pivoted blades and lower bodies which house corresponding driving shafts. The units are releaseably fastened to the beam and in one embodiment, spaced apart supporting elements are fastened to the front side of the beam and a unit is fitted and bolted between elements. In another embodiment, the body of each unit is hollow so that the beam can be passed through units and the latter abutted to one another and secured in place with a single bolt. The driving shaft of each unit is interconnected to adjacent driving shafts by sleeve connectors that form an elongated drive shaft that is parallel and in front of the beam. Corresponding upwardly extending rotary shafts of the rotors have screening caps fastened by bolts and compression springs beneath the caps bear on a ring through which pivot pins extend to cutters. Removing the bolt from each shaft releases the cap, spring, ring, pins and cutters.
